Dissipation-Enabled Operator-Norm Locality Bounds for Bose-Hubbard Hamiltonians
Marius Lemm, Tim Möbus
Closed bosonic lattice systems do not generally admit operator norm Lieb-Robinson bounds uniformly in the initial state. The reason is that the information propagation velocity can…

On Bourgain's approach to stochastic homogenization
Mitia Duerinckx, Marius Lemm, François Pagano
In 2018, Bourgain pioneered a novel perturbative harmonic-analytic approach to the stochastic homogenization theory of discrete elliptic equations with weakly random i.i.d. coeffic…
